HMatrix for projecting from AbsTrackRep parameters to measured parameters in a DetPlane.
Definition: AbsHMatrix.h:37
Contains the measurement and covariance in raw detector coordinates.
Abstract base class for a track representation.
Definition: AbsTrackRep.h:66
A state with arbitrary dimension defined in a DetPlane.
Definition: StateOnPlane.h:47
Object containing AbsMeasurement and AbsFitterInfo objects.
Definition: TrackPoint.h:46
Class for measurements in wire detectors (Straw tubes and drift chambers) which do not measure the co...
virtual bool isLeftRightMeasurement() const override
If the AbsMeasurement is a wire hit, the left/right resolution will be used.
virtual SharedPlanePtr constructPlane(const StateOnPlane &state) const override
Construct (virtual) detector plane (use state's AbsTrackRep).
virtual AbsMeasurement * clone() const override
Deep copy ctor for polymorphic class.
void setMaxDistance(double d)
Set maximum drift distance.
void setLeftRightResolution(int lr)
select how to resolve the left/right ambiguity: -1: negative (left) side on vector (track direction) ...
virtual std::vector< MeasurementOnPlane * > constructMeasurementsOnPlane(const StateOnPlane &state) const override
Hits with a small drift distance get a higher weight, whereas hits with big drift distances become we...
virtual const AbsHMatrix * constructHMatrix(const AbsTrackRep *) const override
Returns a new AbsHMatrix object.
Defines for I/O streams used for error and debug printing.
std::shared_ptr< genfit::DetPlane > SharedPlanePtr
Shared Pointer to a DetPlane.
